PAPER MONEY SORTING AND COUNTING MACHINE Filed April 12, 1949 2 Sheets-Sheet 2 Patented Jan. 2, 1951 PAPER MONEY SORTING AND COUNTING MACHINE Thomas E. Hayes, Washington, .D. 0. Application May 12, 1949, Serial No. 92,879

4 Claims. 1 This invention relates to improvements in machines for sorting and counting paper currency,

such as disclosed in Patent No. 2,429,159, and

liver it to the upper part of the compartment.

The compartment is divided into an upper receiving compartment and a lower storage compartment by a pair of flaps, or shelves, which are pivoted to the side walls and rotatable downward to lie flat against the side walls, to permit the accumulated bills above the shelves to drop down into the lower storage section. In the operation of the machine it is necessary for the operator to place separators into the upper part of the compartments when a predetermined number of bills have been inserted. It is also necessary in case of a miscount to remove the bills from the shelves to run them again through the rollers for a recount. In either of these or other operations in the upper compartment, more than slight pressure upon the shelves has been sufficient to cause the shelves to rock, frequently dumping the bills contained thereon into the lower compartment with the result that all of To overcome this, it was proposed that stops be used to prevent the downward movement, but this was not feasible as the stops of necessity would be located in the path the shelves must travel in their opening movement. The same objection applied to the use of a stop in connection with the conventional solenoid which was used for operating the shelves. For these reasons stops, in their ordinary forms, could not solve the problem.

The object of the present invention is to provide an automatic operating means for dumping the shelves in a machine of the type described, so connected to the shelf linkage that the linkage and operating means together form means to lock the shelves against downward movement so that they will not be displaced when pressure is put upon them.

A more specific object of the invention is to provide a rotary solenoid as the motivating element and connect the shelf operating linkage to 2 the solenoid in such manner that the solenoid forms a, locking element for the shelves.

Other objects of the invention will become apparent from the following description of one practical embodiment of the invention when taken in conjunction with the drawings which accompany and form a part of this specification.

In the drawings:

Figure l is a partial, vertical section taken on the line l--l of Figure 2, through a portion of a money counting and sorting machine as disclosed in Patent No. 2,429,159, showing the present invention as applied thereto;

Figure 2 is a rear view of the shelf operating mechanism, the back of the housing being cut away;

Figure 3 is a horizontal section taken on the line 3-3 of Figure 2, showing the shelves and their operating mechanism in plan; and,

Figure 4 is a side elevation to an enlarged scale of the improved structure of this application, the parts being moved to shelf-dumping position.

As indicated generally above, the money counting machine to which the invention is applied comprises a cabinet I having a plurality of adjacently positioned vertical compartments 2. Each compartment is divided into an upper receiving compartment and a lower storage compartment by means of a pair of hinged shelves 3. Each shelf section is hingedly connected to one side wall of the compartment, and is of such width that when in closed, or horizontal position the two shelves will substantially span the width of the compartment. The bills are fed to the several roller pairs 4 mounted atthe upper front of the cabinet, one pair for each compartment, and therollers feed the bills into the compartment with sufficient speed that the bills will strike the rear wall of the compartment and fall to lie fiat upon the shelves. When a particular batch, or account, has been counted and found correct, the shelves are caused to swing downwardly about their pivots to lie fiat against the side walls, permitting the accumulated bills to drop into the lower section of the compartment.

To enable the shelves to be dumped automatically and simultaneously, each shelf is fixed to its hinge pin 5 to rotate with it. Hinge pins 5 project rearwardly beyond the back wall of the compartments, and each is provided with a slotted lever B. Each lever is engaged by a pin 1 which proj cts from a rock shaft 8 and passes 3 through the slot in the lever. The pins 1 bear against the sides of the slots in the levers so that when shaft 8 is rocked the levers will be rocked, turning the hinge pins 5 and dumping the shelves. It will be noted that the levers 6 controlling the respective shelves of each pair are oppositely disposed so that movement of shaft 8 in one direction will cause the shelves of the pair to swing in opposite directions so that they will drop down to lie parallel with their respective side walls of the compartment. Shaft 8 extends substantially the full width of the cabinet and is supported in bearings secured to the back of a bracket It to thefront oi the abinet b'ack wall. The rotative, element, H of solenoid 9 is {provided with a diskv l 2 mounted upon: its outer end outside of the solenoid housing The disk I2 is connected to a lever l3, mounted on the end of shaft 8, by means of a 1ink l 4;. The attachment'of the to the -lever and disk is such thatwhen the sole'n'oid has reached its limit of travel in one direction, clockwise as here shown, theshelves will be in horizontal billreceiving position and the pesiti'onloi the ;link p'will be a beyond center relationship with respect to the -d-iskv'l'2. .In other words whenthe parts are in this position, downward pressure upon the shelves w-i'l tend to turn the sh aft 8 and'fiever i3 in a counter clockwise direction, as viewed in Figure l, and the lineqof,fprcetransmissionof link l4 will be DGIOVLH'IG center of the, rotative element of solenoid .9 thus tendingto rotate the disk 12 in a clockwisedirection. it cannot do as the solenoid has reached its -l-imit of clockwise rotation 1Wh'en the shelves reach shoriact-ital position, Spring l5, connected to the lever 13 andlthe lihlc l4, urgesjthelink in its lockin direction so; that it will be maintained in'position tolperform its lbckingfunction, H I
